TASTING NOTES
The 2025 Cos d'Estournel Blanc was picked between August 25 and September 3 and matured in just 6% new oak. It is very fragrant and pure on the nose, Anjou pear and wild peach, vanilla pod and light chamomile scents evolving with time in the glass. Fine delineation. The palate is very well balanced, with a silver thread of acidity. Fine tension, quite persistent in the mouth, with a brisk and focused finish, this is a delicious white Cos d'Estournel that, again, will be difficult to resist once in bottle. Drinking Window

The 2025 Blanc, a blend of 56% Sauvignon Blanc and 44% Sémillon, reveals aromas of white fruits, herbs and spice. Medium- to full-bodied, it’s dense and structured with a tensile, more energetic profile than usual, concluding with a citrus-inflected, long and fresh finish.

An incredible wine with electrifying acidity and great depth and concentration. It’s full-bodied and full of character, showing fresh and dried citrus, then honeysuckle and other white flowers. The palate takes off with bright, intense acidity. A pH of just over 3 gives a unique combination of tangy acidity and ripe fruit. Special white. 56% sauvignon blanc and 44% semillon. Best ever?

The 2025 Cos d'Estournel Blanc is a potent, driving dry white. Green apple, pear, mint, white flowers and candied lime are some of the many nuances that develop with a bit of time in the glass. There's gorgeous mid-palate richness here that just needs time to emerge. 2028-2033.
